In late years, ultrasonic surgical aspirators are used in laparoscopic surgery. Their probes' configuration, which is linear shape, encumbers accurate surgical techniques. We propose a bendable probe that can be controlled at someone's discretion. NiTi alloy and ASTA2^[○!R] ware selected as probe materials, because of their high modulus and low Young's modulus. In this paper, we describe an evaluation of vibration properties of two alloys selected as probe materials by measuring their vibration transmissibility. Compared them, ASTA2^[○!R]'s one was more than 5 times as large as NiTi alloy's. We confirmed ASTA2^[○!R]'s vibration property is of service for this new probe.
